Design parametric study of a compound wing-in-ground effect. Ii: aerodynamics coefficients

The aerodynamic behavior of the wing-in-ground effect can be affected by its configuration. This configuration is potentially the most influential parameter for the performance and stability of the wing-in-ground effect craft. As a continuation to the authors’ previous works, in this research, the a...
